Melissa Rycroft: Jason Mesnick Lied About Molly Malaney

After a tumultuous and "historic" season finale of The Bachelor, Jason Mesnick and Molly Malaney say they are extremely happy. Melissa Rycroft? Not so much.

On today's Ellen DeGeneres Show, M-Ry is speaking out for the first time about being dispatched by her Bachelor fiance on national TV and how hurt she was when she discovered that he had been dating runner-up Molly.

When did things fall apart? Melissa says "it was pretty immediate" after the finale that Jason Mesnick realized he didn't want to be with her.

"Once we got back to the real world, we were talking about how [our relationship] was different. He kind of gave up, and I couldn't understand why at the time. Now I do - because I think there was someone else involved."

"And that is where my feelings of betrayal came in," Melissa Rycroft added.

Melissa says their engagement did not end on TV, as it may have appeared to viewers who saw him propose 25 seconds prior, but Jason was still dishonest.

The chemistry between these two faded fast after the finale.

"I knew on the night After the Final Rose [aired], I wasn't getting dumped. We had already ended the relationship and that was mutual."

"I repeatedly asked Jason, 'Is Molly involved in anything?' And when they moved up the taping of the After the Final Rose special [to January], I was thinking to myself, 'Why did we move the taping up? What's going on?'"

"I asked Jason, 'Am I going to be blind-sided by anything? Is there anything you want to tell me?' And he said, 'No, gosh no.' And the second I went out on that stage, he goes, 'P.S. it is Molly.' And I went, 'Bastard!'"

Even as Jason Mesnick initially denied he was dating Molly Malaney, Melissa Rycroft had a hunch something was going on with them.

"Being a girl, you get that feeling," she says.

"Anybody that's been cheated on, you know. Being a woman, I got that feeling, because he just backed away from me, and I knew he had contacted her."

"There had been at least one contact that I knew about, where he was 'checking on her,' and so it was just in the back of my mind. I would just casually ask, 'Are you talking to her? Have you talked to her? Tell me, just be honest.'"

"He kept saying no," she said.

Melissa Rycroft also referenced the e-mail exchange she had with Jason Mesnick "right after we filmed After the Final Rose."

"I instigated it ... and wish I hadn't," she says. "I felt like I needed to apologize for getting that angry with him, but at the same time, I said, 'I hope you know why I got that mad.' We weren't talking at that point, so it was my way off saying, 'This is my closure ... Don't reply back.'"

Asked if she could ever be friends with Jason or Molly, Rycroft says, "No."

"Jason and Molly don't quite have the characteristics of [people] I would want to be friends with," she says. "On a level, they both did betray me. I understand it was a break-up, and I'm not mad about that. We all get broken up with, but to be lied to...."

Rycroft says she is moving on and is even dating a new guy - one ironically named Ty (although she declined to reveal any more details).

"Because of the privacy and everything going on, we haven't really been able to explore a new relationship, but now that everything is over, I'm so excited," she says.

"I've known him for two years and kind of done the dating on-and-off. He has been my biggest rock and supporter throughout this whole process. He's my best friend."

He's a lucky dude.

If you missed it the first time or just like watching slow-motion train wrecks, here's the video of Melissa getting the boot on national TV ...

Iâ€™m thrilled that the California supreme court overturned the ban on gay marriage. I canâ€™t wait to get married. We all deserve the same rights, and I believe that someday weâ€™ll look back on this and not allowing gays to marry will seem as absurd as not allowing women to vote.
